Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.
The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.
Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here’s where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles — making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles — so it appeared to be smaller than the real smaller orange circle.
When young children aged 4 to 6 looked at these tricky pictures, they weren’t fooled — they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time.
As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they’re more likely to fall for this kind of visual trick.

Yearly influenza epidemics can 3 affect all age groups, but the highest risk of complications occur among children younger than age two, adults age 65 or older, and people of 4 age with certain medical conditions, such as chronic heart, lung, kidney, liver, blood or metabolic diseases, or weakened immune systems.
Seasonal influenza 5 easily and can sweep through schools, nursing homes or businesses and towns. When an 6 person coughs, infected droplets get into the air and another person can breathe them 7 and be exposed. The virus can also be spread by hands infected with the virus. 8 transmission, people should cover their mouth and nose with a tissue when coughing, and 9 their hands regularly.
Drugs for influenza are 10 in some countries and effectively prevent and treat the illness. Some influenza viruses develop 11 to the antiviral medicines, limiting the effectiveness of treatment.
Influenza epidemics occur 12 during autumn and winter in temperate regions. Illnesses result in hospitalizations and deaths mainly among high-risk groups. Worldwide, these annual epidemics result in about three to five million 13 of severe illness, and about 250 000 to 500 000 deaths.
Influenza can cause serious public health and economic problems. In 14 countries, epidemics can result in high levels of worker absenteeism and productivity 15 . 16 most people recover from a bout(轮) of influenza, there are large numbers of people who need hospital treatment and many 17 die from the disease every year. 18 is known about the effects of influenza epidemics in developing countries.
The most 19 way to prevent the disease or severe outcomes from the illness is vaccination. Vaccination is especially important for people at higher risk of serious influenza complications, and for people who live with or care 20 high risk individuals.

While it may come as no surprise that genes may help explain 2 some people have many friends and others have 3 , the researchers said, their findings go just a little farther than that.
"Some of the things we find are 4 uncommon," said Nicholas Christakis of Harvard University in Massachusetts, who helped 5 the study.
"We find that how interconnected your friends are 6 on your genes. Some people have four friends who know each other and some people have four friends who don"t 7 each other. 8 Dick and Harry know each other depends on Tom"s 9 ," Christakis said in a telephone interview.
Christakis and colleague James Fowler of the University of California San Diego are 10 known for their studies that show obesity, smoking and happiness spread in networks.
For this study, they and Christopher Dawes of UCSD used national data that 11 more than 1,000 identical(同卵的) and fraternal（异卵的） twins’ genes. Because 12 share an environment, these studies are good for showing the impact that genes have 13 various things, because identical twins 14 all their genes while fraternal twins share just half.
"We found there appears to be a genetic tendency to introduce your friends 15 each other," Christakis said.
There could be good, evolutionary reasons 16 this. People in the middle of a social network could be secret to useful gossip, 17 the location of food or good investment choices.
But they would also be at risk of catching effects from all sides -- in which case the advantage would 18 more cautious social behavior, they wrote in the Proceedings of the National Academy of Sciences.
"It may be that natural selection is 19 not just things like whether or not we can resist the common cold, but also who it is that we are going to come into 20 with," Fowler said in a statement.

The program allows users to display alerts on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.
Owners must report their laptop missing by visiting a website, which sends a message to the model: a red and yellow “lost or stolen” sign appears on its screen when it is started. Under the latest version（版本）of the software, users can also send a spoken message.
The message can be set to reappear every 30 seconds, no matter how many times the thief closes it.” One customer sent a message saying,’ You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.
In the latest version, people can add a spoken message. For example, the laptop’s speakers will say: “Help, this laptop is reported lost or stolen. If you are not my owner, report me now.”
The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs .Owners can remotely switch to an alternative password if they fear that the thief has also got hold of the access details.
If a thief accesses the internet with the stolen laptop, Retriever will collect information on the internet service provider in use, so that the police can be alerted to its location.
Thousands of laptops are stolen every year form homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.
Other security software allows users to erase data remotely or lock down the computer.
小题1:The expression “to give the thief a piece of their mind “can be understood as “_______”
| A．to give the thief an alert mind |
| B．to express the owners’ anger to the thief |
| C．to remind the thief of this conscience |
| D．to make the thief give up his mind |
| A．record the stealing process | B．help recognize the lost laptop |
| C．lock down the computer remotely | D．send a spoken message |
| A．change some access details for switching on the laptop |
| B．turn on the laptop by using the original password |
| C．operate the laptop by means of and alternative password |
| D．erase the information kept in the stolen laptop |
| A．With no Retriever, thousands of laptops are stolen every year. |
| B．A new soft ware provides a means to reduce laptop theft. |
| C．Retriever has helped to find thieves and lost computers. |
| D．A new program offers a communication platform with the thief. |
When you hear a person’s name，repeat it. Immediately say it to yourself several times without moving your lips. You could also repeat the name in a way that does not sound forced or artificial.
Ask the other person to recite and repeat.
You can let other people help you remember their names. After you’ve been introduced to someone，ask that person to spell the name mad pronounce it correctly for you. Most people will be pleased by the effort you’re making to learn their names.
Admit you don’t know.
Admitting that you can’t remember someone’s name can actually make people relaxed. Most of them will feel sympathy if you say. “I’m working to remember names better. Yours is right on the tip of my tongue. What is it again?”
Use associations.
Link each person yon meet with one thing you find interesting or unusual. For example，you could make a mental note: "Vicki Cheng -- tall, black hair. " To reinforce you’re your associations, write them on a small card as soon as possible.
Limit the number of new names you learn at one time.
When meeting a group of people, concentrate on remembering just two or three names. Free yourself from remembering every one. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning just first names. Last names can come later.
Go early.
Consider going early to conferences, parties and classes. Sometimes just a few people show up on time. That"s fewer names for you to remember. And as more people arrive, you can hear them being introduced to others—an automatic review for you.

| C．just their last names | D．as many names as possible |
| A．Tips on an important social skill. | B．Importance of attending parties. |
| C．How to make use of associations. | D．How to recite and repeat names. |
